Bubble CiTea — Restaurant in Manchester

Ordered via app for pick up at certain time. Came to shop at that time, waited additional 10 minutes before approaching the worker as I saw they didn't have my order even in "queue" to be worked on despite numerous customers who came after me being served. His reaction "whoa, thats big order, you have to come in 10 minutes" - it was 4 teas and mind you this was already 15 minutes after my scheduled pick up time.

He had not noticed but I had. I did not want to make him feel uncomfortable so I let it slide. I would love to know what is so funny about someone with autism.. could you please explain? Maybe little immature kids should not be in customer service....

The matcha bubble tea was really bitter, had to throw half away, the chocolate bubble tea was really disgusting and fake tasing, again threw it away. The mango slush was very good though.

UPDATE: I contacted them due to the request below, but they just interrogated me about my purchase and asked for photos of it as if I'd asked for a refund, rather than responding to their request to rectify the issue. Then no response.

Update: I was sent a voucher for two replacement drinks. Went today and tried passion fruit and lychee teas. Was very nice flavour and...
